Be it known that we, JOSEPH H. -McPHEETEns and PHILIP?. GROSS, both' of Palmyra, Marion county, Misf souri, haveinvented certain new and `useful Improveinents Cornshelling Machines; and wehereb'y declare the following to be a full, and accurate description thereof, refereneebeing' had to the accompanying drawings,

`forming part of this specification.l

The natureof our invention consists in construct-ing a`cornsl1ellei', provided witha cylinder, having short, pointed `spikes or projections upon its surface, to revolve' in a curved row or ,series of ovalor-lattened bars placed beneath it, the rounded edges Of said barsbeingv presented towards the'cylinder, and parallel, or nearly parallel to its axis, so that the ears of corn, in passing between the revolyng cylinderv and the bars, will be turned over and over by the points on the cylinder, andthe grain be taken oit' by contact vyith the edges of'the I bars and fall through between them, while the cob is carried forward by the cylinder-pointsandthrown out. i l

Also, in making the aforesaid bars with corresponding opposite-edges, and arranging them in a harlframe -in such a nlanner that'when one edge is damaged 'by Wear, or otherwise, they may be reversed, and the other' edge presented towards the cylinder, .and those in such' partsy of -the set as to be' most exposed to Wear may be made to-change places with those lessexposed. l 4

Also, in supporting and holding the bar-frame upon serrated keys, and by slotted plates, so that itS position relatively to the. cylinder may be changed, and the spade-between the bars and the cylinder, onv eithe'il side., or beneath, may be varied, as the size ofv the ears of corn or other' circumstances may recpiire'.` y I .y j 'And also, in combining with the aforementioned eylinderwand adjustable bar-frame, an endless apron of` rods or bars, as a cob-carrier.

In the accompanying drawings- Figure is a plan of ouriniproved corn-Sheller, and, Figure 2 a vertical section of thesame atthe line of L strong frame, A A, supports the shelling-machinery, being a pulley, `to which driving-'power may be applied. C, a ly-wheel,'to give a more iiniform'motion to the -cylinder D and the pulley E, on thesame shaft,` tobe connected to thefpull'ey vby a orossed'belt, 'gives a'properinotionto theoylindefG, and byit to the,

'endlessapron or cob-carrier H, composed of the barsor rodsja a, connected together the vstraps or belts-oV b,

revolving' on the cylinders or rollers Gr and-I.

h eing lifted when `in operation by, the plates c `c, bolteddon-tn to the frame, v

4through freely Without the cobs. i

.The cylinder D may befcast in three'pieoes, the middle part or shell, and thet-Wo ends, and beheld together by `bolts, O1' 'may be constructed insuch other manner as may bef preferred. It isprovided with projecting points, as shown in the drawings, anditsl shaft turns in boites `supported by the frame vA, and preventedfrom The shelling-barsd d are flattenetL-and have their" rounded" edgesl presented towards the cylinder D, their ends being flattened inV a direction at right angles tov that in n'hieh 4the middle part is-attened, so'th'attheylmay pass down in grooves prouided for that purpose infthe lcurved barffr'ameJ J, theendsA being of such Width that in resting against eachother theparts'may be'kepta proper distance a'part,`orso `as to allo'w Athe grainto drop Figure 3 is a'n lend viewfofoneofftlie shelling-bars, (enlarged,) showing the rounded edgesabove and below the flattened end that is tobe inserted in the groove' ofthe frame. v

By this arrangement the edge of anypresented to the cylinder-can begreadily changed, and bars-trans ferred from one `part of the frame vtdario'thex', so as to expose the different' edges andv diiferent bars to about equal wear. j 4 The two sidesof the bar-frame J J are secured uponthe bars, and s upportedby the screw-bolts .or rods K and L; To remove or insert the bars, the nuts on those rods shouldbeloosened as much as may be foundvnccessary or convenient. The rod Klis held hyeyes in the slotted 'platesN Non the frame A, so'that hy'loosening the sorewswhich pass through the slots andilxold the Aplates Iorli'the frame, the rod may, be adjusted todiferent positions upon the frame, and the bar-frame moved along together with it; while the rod L, resting in notches upon the keys O O, may be raised or lowered bychcnging the position of the tapering keys. This arrangement enables us to adjust the bar-frame and bars in their position relatively to the cylinder D, and to vary the space between the cylinder and the bars at the sides or beneath, as the size of the earsofcor'n or other circumstances may require.

Thecover P, and the hopper Q, formed by it in conjunction 'with the upward projection of the bar-frame, rest upon the frame A as shown by dotted lines. i

'lhe machine being set in motion, and the ears of corn to be shelled placed in the hopper, they descend `between the cylinder and the bars, and being caught by the points on the cylinder, are turned over and over in contact with the bars Where they approach the cylinder, and thus the grain is taken olf the cob, and passes down between the bars, while the cobs are carried forward by the cylinder-points and thrown out upon the cobearrierH, by which they are conveyed ai'vay to such a distance as may be convenient or desirable. The shelledY corn falling upon the inclined planes S and R, runs down into a bin, or such other receptacle as may bcpro; vided for it. v l l The guides T 'l are wedge-shaped pieces, placed within the hopper, one at each side, to turn the ears of corn away from the ends of the cylinder,v in order that when they reach the cylinder or bars they may be free to turn and arrange themselves parallel to the axis of the. cylinder or to the bars. It is obvious that the form and construction of these guides may be considerably varied and yet produce the ciect described.

Having'thus described the construction and operation of a corn-shellerwith our inlprovementsfvrhat we claim, and desire to secure by Letters Patent, isl l. Making the shelling-bars flattened, with roundcdedges, or hat oval in a cross-section, substantially as described.

2. Making. the shelling-bars with corresponding opposite edges, and arranging them in such a manner that the edge of any .bar presented towards the' cylinder,' or the place of the bar in the bar-frame, may be readily changed, substantially as described, and for the purposes set forth.

3. Making the bar-frame adjustable in its position relatively to the cylinder D, substantially in the inode andfor the purposes described.

4. In combination with the cylinder D and adjustable bar-frame J J, we claim the endless apron or cobcarrier H.

5. We alsovclaim vthe guides T T, substantially as and for the purposes described.
